Stainless Steel 1.4016 vs 430
Stainless Steel · grade comparison
Stainless Steel 1.4016 and 430 are both stainless steel grades. Both yield at about 320 MPa — strength does not separate them. 430 is the more ductile: elongation 30% versus 26% for 1.4016. 1.4016 is stiffer (220 GPa vs 200 GPa). On the shop floor, 430 welds better (good vs fair) and 1.4016 sits in a lower cost tier (budget, $) than 430 (standard, $$).
1.4016Choose it when cost is the deciding factor.
430Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
1.4016 vs 430: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
